摘要： A plant for producing cement clinker, comprising as viewed in the direction of materials flow, a heat exchanger to preheat raw meal, a downstream calciner to calcine the raw meal, a rotary kiln to sinter the calcined raw meal, and a clinker cooler to cool the sintered cement clinker. A combustion device which carbonizes, pyrolysis or burns difficult fuels, is embodied as a pot reactor or gooseneck reactor in an inverted U-shape, and is positioned upstream of the calciner on the flow path of the exhaust gases from the rotary kiln to the calciner, and has a gas outlet that opens out above a tertiary-air line of the clinker cooler into the calciner. As a result, it becomes possible to burn fuel which is lumpy and/or has poor ignitability, and the gases from incomplete combustion in the reactor are available in the calciner in gaseous form for further combustion.

摘要： A method of producing cement clinker including the steps of preheating raw meal comprising calcium carbonate in a preheating stage that is preheated by the exhaust gases of a sintering stage connected downstream in the direction of the gas flow, neutralizing the preheated raw meal, sintering the raw meal into cement clinker in a sintering stage, and cooling the cement clinker from the sintering stage in a cooling stage that cools the cement clinker with a gas. The exhaust gases of the sintering stage are combined with the exhaust gases of the neutralization, and the combined exhaust gases are conducted in an open gas circuit. The CO2 emissions are substantially reduced over known systems with CO separation, and the formation of nitrogen oxides by the combustion of atmospheric nitrogen in the oxidative environment of the sintering stage burner is almost completely prevented.

摘要： A roll press for the compression or compacting of granular products. Two detachable rolls separated by a roll gap are driven in opposite directions and mounted on shafts to rotate in a machine frame. The shafts of the mobile rolls are received in bearing housings arranged in a mobile manner in the machine frame. Two respective bearing housings of different rolls, arranged on one side of the rolls, are interconnected by at least one pressure cylinder having at least two working chambers. A method for centering mobile rolls in such a roll press. The at least two working chambers have a force effect acting in opposite directions, and are interconnected in such a way that a pressure medium can circulate between the chambers. In this way, the hydraulic system is positioned in a fixed manner on the machine frame, the rolls nonetheless being mounted in the machine frame in a floating manner.

摘要： A feed device for a high-pressure roller press for the high-pressure comminution of material to be ground, the feed device feeding the material to be ground in a controlled manner into the roller nip between two rollers of the high-pressure roller press. The feed device has at least two rotary valves, the position of which is variable independently of each other. In a refinement of the invention, the feed device also has a shaft which is variable in height above the roller nip. By means of the rotary valves which are variable independently of each other and by means of the height-variable shaft, the feeding behavior of the feed device can be varied during the starting of the high-pressure roller press and during the operation of the high-pressure roller press in order thereby to prevent the high-pressure roller press from vibrating and to ensure optimum operation of the high-pressure roller press.

摘要： A method for the production of an annular casing for the press rollers of roller presses for the pressure comminution of particulate material, the outer surface of which casing always has a high degree of hardness and consequently a high wear-resisting capability, but the radially inner region of which casing has a lower degree of hardness to avoid casing ruptures. The annular casing is cast of nodular cast iron with at least the alloying elements Ni and Mo. The cast body is given a bainitic structure with residual austenite by a subsequent heat treatment followed by controlled cooling. The outer surface is constantly re-hardened during use via pressure loading such that martensite is constantly formed in boundary layers of the outer surface.
